GAS-BURNER AND REGULATING-VALVE Fon BOILERS.

Specification of T etters Patent.

Patented Aug. 1, 1905.

Application filed January 11, 1904. Serial No. 188,580.

To a/ZZ whom it mayconcern:

Be it known that I, JAMES W. WILSON, a resident of McKeesport, inthe county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Gas-Burners and Regulating-Valves forBoilersg'and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a gas-burner and regulating-.valve for steam-boiler furnaces; and one of the objects is to so arrange the gas-` burners, supply-pipes, and regulating-valve as not to interfere with the coal-firing of the furnace.

Another object is to so construct'and arrange the burners and regulating-valve that the burners need not be moved, and hence can be made as large as required and so as to avoid leakage of gas.

Prior arrangements for gas-firing of steam-l boiler furnaces are such that they interfere with coal-iiring, thus making it almost vimpossible lto keep up steam if the gas-'supply is shut off.

` The object of my invention is to providean arrangement for'the gas-firing of steam-boiler furnaces whereinthe above objections are valve'for this purpose so constructed thatthe seat and valve part can be easily removed and replaced and so lthat the dust in the gas is collected and easily' removed from the gas-main.

The invention also consists in details of con- L struction which will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a front elevation of boilers equipped with my invention. Fig.2isaverticalsectionthrough the same on the line 2 2, Fig. l; and'Fig. 3 is a similar section on the line 3 3, Fig. 1.

My invention may be applied to any known form of steam-boiler., and Yin the drawings it has been shown applied to a well-known type of water-tube boiler, the drawings, however, showing only a portion thereof, the tubes becoal-stking.

ing indicated at 1, the headers at 2, and the` drumat 3'. These will all be mounted, as is the custom, and inclosed in asuitable chamber. The combustion-chamber isv shown at 4, and this may be of any known shape and construction of such chambersor it may be omitted entirely. It is provided with the grate 5 for burning .coal and similar fuel and firingdoorsl 9, thus avoiding any sliding joints and the danger of leakage.

The supply-pipe 9 is suitably supported I overhead so as not to interfere with the coal. I

stoking of the furnace. The regulating means are all placed at the side of the boilers, so a's to leave a clear space in front of the same for As shown in the drawings, each end of the supply-pipe 9 is vconnected to a valve-chamber 10. The valve-chamber 10 is comprised in a casing having an outlet-openv ing in one side wall communicatingwith the supply-pipe 9 and a supply-opening in its top communicating with the branch main 12 and regulated by a'suitable valve.- The branch main 12leads to the supply-main 13. All of these parts are arranged overhead, so as to be out of the way of the stokers.

The valve consists of a bell 15, seating on an overhead seat 16 and arranged to open byl moving downwardly; Any suitable operating means for this valve may be used, and in the drawings there is shown a rod 17, connected to the bell and extending through a stuliing-box in the gasmainthe upper end of this rod being connected :to a lever 18, having thereon a counterweight- 19 and a regulating-rod 19a. Any other suitable means, however, might be employed.

The valve-seat 16 is clamped between a iange 20a on the lower portion of the sup-y ply-main and .a iiange 2O on the upper portion vof the valve-casing 10, vso that said seat can be removed and changed from the outside without disturbing the valve-chamber.` The bell 15 is also adapted to be readily removed, and to this end the valve-chamber is provided on one side with a door 21 of sufcient size to enable the bell to4 be removed and changed. The valve-chamber is made sufficiently large so that when the valve is opened the gas will have ample room to pass. Adamper or valve 23 will be provided in the branch main 12, so that the gas may be shut off while the valve or valve-seat is being changed.

When the regulating-valve is closed, the dust which always is found in gas will accumulate above the valve, and when the valve is open this dust will fall down into the valvechamber. I make provision for removing the same. Underneath the valve-chamber is the dust-catcher 24, which consists of a suitable ing carried into the supply-pipe 9. rlhe dust which is carried by the gas will also have a tendency to settle down into this dust-chamber, from which it can be periodically removed by means of the valve 25.

My gas supply and regulating arrangement is such that `a clear space is left in front of the boiler-furnace, thus not interfering with the stok-ing of the furnace with coal. Furthermore, the burners 8 are immovable, so that no sliding joints are present, and leakage is thus avoided, the regulation of the gassupply being accomplished by the valve in the supply-pipe instead of by removing the burners, as heretofore. This regulating-Valve, furthermore, is so constructed that it can be readily changed, and provision is also made for clearing the gas of dust.

What-I claim is- 1. A gas-burning steam-boiler furnace comprising a combustion-chamber, an overhead supply-pipe, burners connected thereto and projecting into the combustion-chamber, a valve in said supply-pipe at one side of the boiler-furnace and serving to regulate the flow of gas to the burners, and a dust-collection chamber underneath said valve and provided at its bottom with an opening for removal of the dust.

2. A boiler-furnace comprising a combustion-chamber, gas-burners projecting into the same, a supply-pipe connected to the burners, avalve-chamber having an opening in its side to which said supply-pipe is connected, a downwardly-opening valve in said valvechamber, and a dust-collecting chamber connected to the lower part of the valve-chamber and located below the opening leading to the supply-pipe and provided at its bottom with a cleaning-opening.

3. A steam-boiler furnace -comprising a combustion-chamber, an overhead gas-supply pipe, burners connected to said pipe and projecting into the furnace-chamber, a valvechamber located at one side of the boiler-furnace and having an opening in its side communicating with the supply-pipe and havingan inlet-opening through its top, a downwardlyopening bell for regulating said inlet-opening, and a dust-collecting chamber connected to the lower part of the valve-chamber and provided with a cleaning-opening.

4. A steam-boiler furnace comprising a combustion-chamber, an overhead gas-supply pipe, burners connected to said pipe and projecting into the furnace-chamber, a valvechamber located at one side of the boiler-furnace and having an opening in its side communicating' with the supplypipe,a regulatingvalve in said valve-chamber, a dust-collecting chamber connected to the lower part of the valve-chamber and located below the opening communicating with the supply-pipe, and a valve-controlled cleaning-opening in the bottom of said dust-collecting chamber.

5. A steam boiler furnace comprising a combustion-chamber, burners projecting into the same, a gas-supply pipe connected to said burners, a valve-chamber in said supply-pipe, a valve-seat in said chamber, a downwardlyopening bell cooperating with said valve-seat, a door in the side of said valve-chamber to permit the removal of said bell, and a dustcollecting chamber connected to the lower part of the valve-chamber and provided with a cleaning-opening.

6. A steam -boiler furnace comprising a combustion-chamber, burners projecting into the same, a supply-pipe connected to said burners, a valve-casing having an opening in its side communicating with the supply-pipe and having a gas-inlet through its top, adownwardly-opening bell for regulating said inlet, a door in the side of the valve-casing to per mit the removal of said bell, adust-collecting chamber connected to the lower part of said valve-chamber and located below the opening communicating with the supply-pipe and provided with a cleaning-opening in its lower end, and means for closing said opening.

7. A steam-boiler furnace comprising a combustion-chamber, a grate therein, a firingdoor above said grate, an overhead gas-supply pipe, burners connected thereto and projecting into the combustion-chamber above the top of the door, a regulating-valve in said supply-pipe at one side of the boiler-furnace, a dust-collecting chamber underneath said valve, and a cleaning-opening in the bottom of said dust-collecting chamber.
